Understanding Bra Sizes in the UK
Bra sizes in the United Kingdom differ slightly from US and European systems, making it important to understand the standards before purchasing. UK sizing typically includes:
- Band Size: The number indicating the circumference around the ribcage, just beneath the bust. UK band sizes commonly range from 28 to 50 inches.
- Cup Size: Represented by letters (A, B, C, D, DD, E, F, FF, etc.), cup size measures the difference between bust measurement at its fullest point and the band size. UK cup sizing sometimes extends beyond US sizes, including double letters for larger sizes.
The UK Bra Size Online Calculator helps bridge the gap between measurements and actual bra sizing, ensuring a precise fit across different brands.
Why Accurate Bra Sizing Is Crucial
- Enhanced Comfort: A properly fitted bra reduces pinching, digging, and rubbing.
- Improved Posture: Supportive bras alleviate back and shoulder strain.

Additional Information
- Measure Your Band: Use a soft tape measure around your ribcage, just under your bust. Ensure it is snug but comfortable.
- Measure Your Bust: Measure around the fullest part of your bust, keeping the tape level and not too tight.
- Calculate Cup Size: Subtract the band measurement from the bust measurement. Each inch difference corresponds to a UK cup size (1 inch = A, 2 inches = B, 3 inches = C, etc.).
- Check Sister Sizes: If the band feels tight or loose, adjust the band and cup proportionally to maintain cup volume. Example: 34C → 32D or 36B.
- The Band is Key: The band provides most of the support. It should sit level across the back and feel snug on the loosest hook.
- Center Gore Fit: The center panel between cups should lie flat against the sternum.
- Proper Containment: All breast tissue should be inside the cups, with no spillage or gaps.
- Regular Measurement: Body changes mean bra size can change. Check every 6-12 months.
- Quickly identifies your correct UK bra size.
- Reduces discomfort and improper fit issues.
- Helps with online and in-store shopping.
- Supports understanding of sister sizing options.

UK Online Bra Size Calculator – Frequently Asked Questions
How can I ensure the UK online bra size calculator gives me an accurate measurement?
For the most accurate calculation, always measure your band size first by wrapping the tape measure firmly directly under your bust, and then measure your cup size loosely around the fullest part of your chest. Enter your measurements into the tool in inches, as UK sizing is traditionally based on Imperial units.
What is the primary difference between UK and US bra sizing from a calculator result?
The main distinction lies in the letter progression after a D cup. While band sizes are generally similar, the UK system uses double letters like DD, FF, and GG as cup volume increases, whereas the US system frequently uses triple letters (DDD) or jumps to new single letters (G, H) much sooner.
Why does my calculated back size feel different from the one I currently wear?
Bra fitting experts recommend that 80% of support should come from the back band, which should fit snugly. If your calculated band is smaller, it's likely because your current band is stretched or too loose, causing the bra to ride up and offer poor support. A snugger fit from the correct size is essential for proper lift.
If the calculator suggests a different cup letter, should I also change my back band size?
Not necessarily. If your calculated cup size changes but the band size (the number part) remains a good, snug fit, you should stick to the same band size and just adjust the cup letter. Only change the band size if it is physically uncomfortable or rides up.
How does my "sister size" relate to the bra size determined by the calculator?
A sister size is an alternative size that maintains the same cup volume on a different band. For example, a 34C has the same cup volume as a 36B (one band up, one cup down) or a 32D (one band down, one cup up). The calculator provides your primary size, but sister sizes offer flexibility for comfort across different brands and styles.
How often should I use the size finder to check my dimensions for new lingerie purchases?
It is highly recommended to re-measure your dimensions every six to twelve months, or any time you experience significant changes in weight, fitness level, or hormonal fluctuations (such as pregnancy). Body shape changes mean your optimal size for support and comfort can shift over time.
